Custom 5-axis CNC motorcycle clutch hub

Product Overview & Machining Capabilities

The custom motorcycle clutch hub functions as the primary torque transfer component between the engine basket and the transmission shaft under high-RPM loads. Our China factory utilizes 5-axis CNC machining centers to mill high-density aluminum billets, achieving exact internal spline geometries and lightweight pocketing. As a direct motorcycle clutch hub manufacturer, we control runout and concentricity deviations strictly to prevent clutch basket vibration during engagement and disengagement cycles.

Video: Live Machining Demonstration: 5-Axis CNC Milling

The video left demonstrates the simultaneous 5-axis CNC machining process of the AL7075-T6 motorcycle clutch hub. By adopting a single-setup machining strategy, we eliminate secondary fixturing deviations (datum shifts). This ensures the spatial geometry between the internal transmission splines and the external mounting interface is maintained within strict tolerances.

Process Highlights in Video:

Machining Strategy: Simultaneous 5-axis interpolation for complex lightweight pockets.
Critical Feature Control: Direct milling of internal splines with continuous toolpath optimization.
Engineering Benefit: Guarantees ≤ 0.01mm concentricity, preventing drivetrain vibration under high-RPM clutch engagement.

Quality Control & Inspection Standards

We enforce strict metrology protocols across the entire production sequence. Each batch undergoes dimensional verification using Zeiss Coordinate Measuring Machines (CMM) and optical profile projectors. Our facility operates under an ISO 9001:2015 certified quality management system. Final deliveries include material test reports (MTR), surface hardness certificates, and full First Article Inspection (FAI) documentation.

Application Industries

Engineered for high-stress power transmission environments, these machined hubs integrate directly into continuous duty drivetrains. Primary applications include professional racing motorcycles, off-road motocross bikes, heavy-duty commercial ATVs, UTV drivetrains, and aftermarket performance transmission assemblies.

Frequently Asked Questions (FAQ) Regarding Custom Clutch Hubs

01.What is the minimum order quantity (MOQ) for custom hubs?

As a flexible manufacturer, we support low volume runs. Our MOQ starts at 1 unit for prototype validation, scaling up to 10,000+ units for full-scale production.

02.Which aluminum grades do you recommend for clutch hubs?

We recommend AL7075-T6 for its high tensile strength and fatigue resistance, which is standard for transmission components. AL6061-T6 is also available for applications requiring high corrosion resistance.

03.Can you achieve hard anodizing on the clutch hub surface?

Yes. We provide Type III hard coat anodizing up to 50 microns to increase surface hardness, reduce friction, and prevent rapid wear on the spline interfaces.

04.Do you provide First Article Inspection (FAI) samples?

We issue full FAI reports with our initial prototype runs. Full production does not begin until you approve the physical sample and the dimensional verification data.

05.What is the standard lead time for a new custom order?

Upon CAD file approval, CNC prototypes require 5 to 7 days. Low-volume batch production typically takes 10 to 15 days, depending on secondary surface treatments.

06.How does your factory ensure spline concentricity during machining?

We machine the inner and outer diameters in a single setup using 5-axis CNC centers. This eliminates re-fixturing errors, maintaining concentricity deviations below 0.01mm.
